The City Air Cleaner filters up to 85 percent of harmful ambient pollutants such as fine dust particles and gaseous substances like nitrogen oxides, and ground-level ozone from the ambient air and creates a comfort breathing zone with better air quality.
The casing design can be executed to match customer's needs:

• neutral design corresponding to the installation site
• corporate branding for company premises
• luxury variant for exclusive working and living environments

The Breathe Easy Systems with a volume flow of up to 8,000 cubic metres per hour, the M-8 air filter ensures a continuous supply of freshly cleaned air. The unit can clean an area of more than 500 square metres virus-free at an air exchange rate of six and a room height of 2.50 metres.
Effective air purification is the key to minimising the risk of infection with virus-containing aerosols indoors, as has been demonstrated in numerous studies. In premises where permanently installed ventilation and air-conditioning systems are lacking or provide only insufficient air quality, professional mobile air purifiers are a good solution.

Several City Air Cleaners work in combination to form a modular, scalable system for active management of urban air quality. Simulations of the real environment are used to determine an effective tailor-made air filter solution - for emission hotspots and constructionally and meteorologically caused accumulation points for pollutants. The large infoscreens on the sides of the City Air Cleaners allow for local air quality infotainment as well as local traffic and event information or third-party advertising. The City Air Cleaner is universally applicable. There are different models for tailor-made air cleaning solutions:

Effective Proven filtering of pollutants such as fine dusts, viruses and bacteria from the drawn-in air.

Modular Multi-stage filter system for flexible adaptation of filter media to specific local air contamination scenarios.

Efficient Ideal ratio of cleaning performance to power consumption, operating, and maintenance costs.

Mobile Flexible and easy set up without foundation and ready for operation at short notice.

Intelligent Demand-oriented control of the system with monitoring of the operating performance for preventive maintenance.

Low noise Demand-driven operation under consideration of the local pollution and noise levels.

Reduce elevated pollutant concentrations

City Air Cleaners help to reduce elevated pollutant concentrations locally in the short term and reduce further spread. At the same time, they ensure that filtered air is supplied to endangered immission locations.

• Available technology:to immediately and actively reduce the pollution of the population in places with particularly poor air quality
• Active contribution to meeting statutory air quality standards: in zones with excessive air pollution in relation to the prescribed values
• reduction of local pollutant concentrations:by direct extraction of the pollutants at source
• Measurable improvement in air quality:in the vicinity of the city air cleaners by effective filtering of pollutants from the ambient air sucked in
• Reduction of pollution in the air we breathe:in the sphere of action of city air purifiers by active dilution of the ambient air

Technology

Innovative solution with proven technology

The City Air Cleaner represents an innovative solution for the effective technical cleaning of air volumes contaminated with pollutants for defined zones in urban environments. When designing the filter technology and air duct, we rely on best-in-class technology from internationally renowned filter and ventilation manufacturers.

1. Filtering unit : The heart of the City Air Cleaner are the synchronously operating multi-stage filter units. We use certified quality filters with maximum performance, taking into account cost-efficient operation and total life cycle costs.Customised selection of filter media according to the type and concentration of the pollutants.Customised selection of filter media according to the type and concentration of the pollutants
2. Pre filter:Pre filter-The wear-free stainless steel mesh of the pre-filters prevents sand, dust, flying plant parts and small particles and water from entering the main dirt filter media system. It increased service life of the main filters,Easy to clean, Protection against vandalism
3. Airflow: High air absorption capacity and even distribution of cleaned air. The primary control variable for the overall cleaning performance is the airflow volume. The City Air Cleaners clean only as much air as required, by means of a demand-driven system control. The fans are designed for continuous operation 24/7. For this reason, special attention is paid to energy efficient operation.On the air outlet side, in addition to the housing fins, air-guiding elements ensure an even diffusion of the cleaned air flow.
4. Sensors: for monitoring pollutant concentrations.Pollutant sensors (e.g. particulate matter PM10, PM2.5 or nitrogen dioxide) can be integrated to monitor the air quality at the air inlet and air outlet side. This allows the air filter system to be controlled according to requirements in a demand-driven operation mode.
5. FISPL Service Cloud: System control and monitoring.The City Air Cleaners are operated automatically and offer remote control and monitoring. In order to keep energy consumption as low as possible, predefined cleaning intervalls based and integrated sensors ensure demand-driven operation. The data of a City Air Cleaner system is automatically transmitted to the Purevento Service Cloud around the clock, all year round. There they are stored, processed and visualised centrally.

Vertical airflow for rapid downward discharge of aerosols containing viruses

Creates local breathing zones with high air quality through the use of HEPA filters and active guidance of the air flows through the roof construction. The special feature of our air filters is the supply of purified air from above, analogous to the airflow in an aircraft. This vertical air flow supports the natural process of sedimentation of airborne particles.

• Purified air is discharged directly into the breathing zone, and has no opportunity to mix with contaminated ambient air
• Exhaled air is continuously discharged downwards and directly sucked in by the unit for purification
• Aerosols that are harmful to health do not spread further due to vertical airflow

Active contribution to air quality levels on road-side

Achieves the best air quality management effect directly at the point of emission. On a busy road, the device can extract the fine dusts and nitrogen oxides emitted by the vehicles directly at the source and filter them out of the air stream. This prevents the harmful pollutants from spreading into the environment.

The cleaned air is slowed down and released on the other side of the City Air Cleaner. The constant flow of freshly cleaned air improves the ambient air on the pavement by displacing the existing polluted air immediately behind the city air cleaner. At the same time it dilutes the prevailing pollutant concentration in the ambient air on the outlet side.

Applications :Urban pollution hotspots

For effective absorption of pollutants on a busy road, City Air Cleaners are ideally placed on both sides of the road.

There are three different areas of application in which City Air Cleaners can make an active contribution to air quality management:

• Zones with particularly high pollutant emissions
  Primary air pollutants such as car exhaust gases and fine dust caused by tyre or brake wear can be directly attributed to the polluters. Avoiding them is the best solution. If this is not possible, it is best to remove them directly at the point of emission. By directly extracting and filtering out the primary pollutants from the ambient air, the formation of secondary air pollutants is also prevented.
• Zones with accumulation of high concentrations of pollutants
  In complex reactions in the atmosphere, additional gaseous pollutants and suspended matter are formed from primary emissions. The accumulation and distribution of these pollutants depends directly on weather conditions. Elevated levels of particulate matter are a problem, especially in winter when weather conditions are poorly exchanged. Unfavourable structural constellations can also contribute to this phenomenon.
• Zones with increased air quality requirements :Children and elderly persons, as well as people with respiratory diseases such as asthma, are particularly vulnerable in large cities due to poor air quality. Creating comfort breathing zones with better air quality in heavily polluted places where these groups of people regularly spend long periods of time, such as schoolyards, playgrounds, seniors residents, or public transport stations, is a good investment in health and well-being.
